Motherboard goes ping on my Dell Dimension 5000

Shortly after a graphics card upgrade last night, I ran up Windows and then the blue screen of death and my pc wouldn’t start up.

Then it slowly got worse until it appeared that the motherboard had given up the ghost. I got on to the folks at Dell and I have a replacement Motherboard on the way.

First time I’ve had a big problem with my old Dimension 5000, and I’ve upgraded and replaced bits over the years with no problem. Now I’ve got the Motherboard to replace. Eek.
